摘要 采用两级解调的方法,优化了WDM/SDM光纤光栅传感复用系统的解调规则,探索了采用双解调系统,同时对光纤光栅传感阵列进行解调以提高传感系统解调速度的方法.在系统设计中采用PetriNet理论来解决多解调系统协调运行的问题·通过构建双解调四通道的布喇格光纤光栅应变传感复用系统验证了多解调复用技术的可行性,采用排队论理论,模拟仿真了双解调系统的性能·理论分析和实验表明双解调系统的平均等待时间比传统的解调方法的平均等待时间低一个数量级· With two level demodulation, the demodulate rule of WDM/SDM FBG sensing system was optimized. To improve the demodulated speed of sensing system more, a FBG sensing multiplexing technique with muti-demodulate device was proposed. Petri net theory was used to sovle the harmonize problem of the technology. In order to demonstrate the feasibility of the multi-demodulate technique, a FBG sensing system with four sensing channels and two F-P filters were studied. The performance of the technique was analyzed by using Queuing Theory. The average delay time of the double demodulate system is lower one magnitude order than the conventional ones.
